Therefore the return on investment on a R100 000 weighted average balance is:

[ R6 000 (from B) / R100 000 (from A) ] *100 = 6%

Once the profit calculations have been performed and approved by the AIB management and Shari'ah Supervisory Board, the profit amounts are deposited into customers’ respective accounts on 25 January 2X02.

Any accounts opened after the financial period (31 December 2X01 as per the example) receives their profit share from the next financial period. Any accounts closed after 31 December but before 25 January do not receive any profit share.
